Application filed January 30, 1920. Serial No..355,238.

To all whom it may concern:

Be it known that we, JOHN DIXON and JOHN M. SHAFFER, both citizens of the United States, residing, respectively, at Monaca, Beaver county, Pennsylvania, and

New Brighton, Beaver county, Pennsyl vania, have invented a new and useful Improvement in Apparatus for Coating Castings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which:

Figure 1 is a plan view, partly broken away, of one form of apparatus embodying our invention.

Fig. 2 is a view partly in side elevation and partly in, sectional elevation, and also partly broken away, of the apparatus shown in Fig. 1.

Fig. 3 is a section on the line III-III of Fig. 2.

Fig. 4: is a detail sectional View. s

' Figs. 5 and '6 are respectively a plan view and side elevation of another form of apparatus, both views being partly broken away, and

Fi 7 is an end view of the apparatus D shown in Figs. 5 and 6.

Our invention has relation to apparatus for use in coating metal castings and is designed to provide means whereby this work may be done-with a minimum of manual handling of the castings to be coated, and in a much more rapid and economical manner than has heretofore been possible.

The invention has been particularly designed for use in applying the first coatings to the covers of enameled metal flush tanks, but may be used for various other articles.

The usual practice heretofore in coating such articles has been to support them in a position in which one side is to be coated and then lift them and turn them to a position to enable the other side to be coated.

This involves considerable manual labor.

By our present invention, we provide means by which a plurality of the castings can be placed upon a movable support or barrow in position to have one surface of each of the articles coated; and by a simple turning movement, without lifting, the articles may be moved to a position in which their opposite surfaces can be coated.

the usual manner.

Y Referring first to that form of our invention shown in Figs. 1, 2, 3 and 4, the support is in the form of'a barrow, preferably mounted upon caster wheels 2 and having its side frames 3 provided each with a plu rality of spaced projections 4 having their end faces inclined in opposite directions, as

indicated at 5. The lower ends of each adjacent pair of inclines are separated by a space; and at the center of the barrow are arranged a series of upwardly projecting pins or posts 6, one of which extends upwardly at each of these spaces and to a height preferably'above the top ofthe projections 4.

The numeral 7 designates a longitudinally extending bar mounted for endwise movement in suitable guides 8 on the barrowand which is adaptedto be given a limited endwise reciprocating movement by any suitable means. For this purpose we have shown the levers 9 pivoted at 10 to the end portions of said bar and extending upwardly through slots 11, the edges of which act as a fulcrum for the lever.

12 designates springs which are arranged to assist in the returnmovements of the bar, said spring acting in tension in one direction and in compression in the opposite direction. Pivotally connected to this bar are a SGIlQS of upwardly extending fingers 13, one adj acent to each of the posts'6, and which pass upwardly through the loose guides 14 on the central frame member 15 of the barrow.

The castings to be coated, and which are marked A, are placed upon the barrow in the position shown at the right hand end of Fig. 6; that is to say, with their lower edges resting on the barrow adjacent the lower end of the inclines 5, and with their upper portions resting against and supported by the central posts 6. In this position the inner faces of the castings are accessible to coating operations, which are usually done by means of an air brush or slush gun in After these surfaces have been coated, the operator, by means of either of the levers 9, moves the bar 7 longitudinally in a manner to first turn one casting of each pair of castings over backwardly against the adjacent inclined supporting surfaces 5, as shown in Fig. 2; and then move said bar in the reverse direction to throw the remaining castings over against the opposite inclines 5. In this position the other surfaces of the castings can be readily coated.

The castings can be placed on the barrow in the cleaning room in their first described positions, and the barrow then taken to the coating room. The operator in the coating room can coat one surface of the castings without any handling of them whatever; and to enable him to coat the other surfaces, all that is required is a simple actuation of the lever 9. In this manner he is entirely relieved of in any way lifting or handling the castings. i

.In Figs. 5, 6 and 7, we have shown a simple form of our invention in which the shifting bar 7 is omitted, and it is necessary for the operator to manually turn the castings from the position shown at the right hand end of Figs. 5 and 6 to the positionshown at the left hand end of said figures. In this form we have shown the barrowas pro vided with supporting legs 16 instead of caster wheels, but the latter, or any other suitable wheel supports, may be' provided if desired. The parts shown in these figures are given the same reference characters as the corresponding parts in the figures first described with the letter a afiixed thereto.

It will be readily understood that the form of the support or barrow maybe widely changed without departing from the spirit and scope of our invention asidefined in the appended claims.

We claim:

1. Apparatus for use incoating castings, comprising a supporting device having supports arranged in pairs and arranged to support two castings in oppositely inclined positions, and other supporting members arranged intermediate thesupports of each pair of the first named supports and adapted to hold said castings in other positions, substantially as described.

2. Apparatus for coating castings, comprising a portable barrow having inclined supports thereon arranged in pairs, and upright supports arranged one between'each pair of inclined supports, substantially as described. r r

3. Apparatus for coating castings, comsupports thereon arranged in pairs, and upright supports arranged one between each pair of inclined supports, together with shifting means for shifting the castings relatively to said supports, substantially as described.

5. Apparatus for coating castings, comprising a portable barrow having inclined supports thereon arranged in pairs, and upright supports arranged one between each pair of inclined supports, together with shifting means adapted to shift the castings from one of said positions to the other, substantially as described.

6. Apparatus for coating castings, comprising a portablebarrow having inclined supports thereon arranged" in pairs, and upright supports arranged one between each pair of inclined supports, together with shifting means adapted to shift the castings from one of said positions to the other, said means comprising an endwise movable memher having shifting fingers, substantially as described.

In testimony whereof we have hereunto set our hands.
